Abstract
The invention discloses a method for reducing screen flickers. The method is characterized by comprising the following steps of: judging whether pixel points included in a display content to be changed exceeds a preset threshold or not; and protecting other display contents of the screen while the pixel points included in the display content to be changed is less than the preset threshold.
Description
Technical field
The present invention relates to integrated circuit fields, in particular to chip drives Electronic Paper display packing.
Background technology
Because Electronic Paper is with low cost, erasable flexible folding, once show characteristic such as to keep to make it obtain using very widely for a long time.
Yet because the characteristic of Electronic Paper itself has determined that its refresh rate can not be very fast., a fritter content need the content of a whole screen all will upgrade once when need changing.Iff has only one or several pixel content to change and other guide is constant, might be because wrong this not content change of change that cause of read-write cause occurring showing mistake when carrying out full frame renewal.
Summary of the invention
The invention provides a kind of method that reduces screen flicker, purpose is to solve problem.
For achieving the above object, this provides a kind of method that reduces screen flicker, it is characterized in that, may further comprise the steps: judge whether the pixel that displaying contents to be changed comprises surpasses predetermined threshold; The pixel that displaying contents to be changed comprises is less than said predetermined threshold, with other displaying contents protections of screen.
Preferably, said predetermined threshold is 1 or 16 pixels.
The above embodiment of the present invention adopts the method with immovable displaying contents protection, has solved to refresh among a small circle to show the problem of makeing mistakes, and has solved the problem of accurate control, has reduced the flicker of the nonessential pixel of screen.
Description of drawings
Below with reference to accompanying drawings specific embodiments of the present invention is explained in more detail, in the accompanying drawings:
Fig. 1 is a kind of process flow diagram that reduces a concrete embodiment of method of screen flicker of the present invention.
Embodiment
Each pixel of Electronic Paper all can corresponding capsule, comprises the chemical substance of show white and black respectively in the capsule, can demonstrate different gray levels through loading different pulse voltage.
The present invention provides a kind of method that reduces screen flicker, and specifically please referring to shown in Figure 1, Fig. 1 is the display packing process flow diagram of a specific embodiment of the present invention, and said method specifically may further comprise the steps.
Said predetermined threshold is 1 or 16 pixels.
In the process of once upgrading screen display content, to experience following operation.
Master control storage write operation (HMW, Host Memory Write) is used for content to be displayed is write the image display buffer by data bus.
Upgrade buffering for synchronous operation (UBS; Update Buffer Synthesis) is used for GTG and the GTG of content to be displayed of the present displayed content of contrast images display buffer, the gray scale variation value that obtains write in the renewal index buffering of said image display buffer.
Show that output function (DO, Display Output) is used for refreshing the pixel on the electronic-paper display screen according to the renewal index buffering of image display buffer.
Said demonstration output function particular content comprises electronic-paper display screen is carried out line scanning; When scanning regional that aforementioned displaying contents changes; Renewal index buffering in the inquiry current time image display buffer; Obtain the gray scale variation value of corresponding pixel points, search the gray scale voltage pulse meter, and this pixel is loaded corresponding potential pulse according to lookup result.
Iff is to change displaying contents among a small circle, then in upgrading the process of buffering for synchronous operation, and the GTG of pixel to be changed in the comparison among a small circle only, and the content protecting of other parts is got up, just do not change their demonstration GTG.So just avoid the mistake that in the read-write process, occurs, also avoided unnecessary gray scale variation, practiced thrift valuable electric weight.
Obviously, under the prerequisite that does not depart from true spirit of the present invention and scope, the present invention described here can have many variations.Therefore, the change that all it will be apparent to those skilled in the art that all should be included within the scope that these claims contain.The present invention's scope required for protection is only limited described claims.
Claims (2)
1. a method that reduces screen flicker is characterized in that, may further comprise the steps:
Judge whether the pixel that displaying contents to be changed comprises surpasses predetermined threshold;
The pixel that displaying contents to be changed comprises is less than said predetermined threshold, with other displaying contents protections of screen.
2. display packing according to claim 1 is characterized in that, said predetermined threshold is 1 or 16 pixels.
